Lecture

Bernhard Brandl, the new Leiden Professor of Infrared Astronomy, is developing instruments for the world’s largest telescopes. These telescopes can be used to observe objects in space that are more than 13 billion years old. Brandl will deliver his inaugural lecture on 26 September.

SRON Netherlands Institute for Space Research is moving. In 2021, the Utrecht branch will settle in South Holland. Assistant professor at TU Delft, Akira Endo leads a project that builds a state-of-the-art instrument for astronomical research. ‘SRON is the key to go from proof-of-concept to a science-grade…

Can astronomers mitigate climate change? This is what Leiden astronomer Leonard Burtscher and his colleagues discussed at the annual meeting of the European Astronomical Society. For the second year in a row, the meeting was online. And according to Burtscher, it should stay that way. During a special…

Smart algorithms and powerful processors are just as essential for astronomy as big telescopes. Astronomers at Leiden University therefore constantly operate at the interface between astronomy and data science.

With new algorithms and supercomputers, an incredibly detailed radio map of the universe was created. Now astronomers can look at radio data of galaxies with much more precision. This was published in Nature Astronomy by Leiden PhD student Frits Sweijen and colleagues.

An international team of scientists including Leiden's Joe Callingham has discovered nineteen red dwarf stars that unexpectedly emit radio waves. The outbursts possibly originate from interaction with exoplanets. The results of the research appear in two scientific publications.

After almost twenty years the record for the most distant radio galaxy has been broken. A team of astronomers led by Leiden PhD candidate Aayush Saxena has discovered a radio galaxy from the time when the universe was just one billion years old. The galaxy is at a distance of 12 billion light years…

A moon rock from the Apollo 17 mission, antique globes and the cosmos according to Wassily Kandinsky. Ewine van Dishoeck, Professor of Molecular Astrophysics, has put together an impressive exhibition at Rijksmuseum Boerhaave.

This summer, the Universe is closer than ever. With the online astronomy summer programme Space in Your Living Room!, the Leiden Observatory brings astronauts and Leiden astronomers to the homes of children all across Europe.

An international team of astronomers has published a map of the sky showing over 25,000 supermassive black holes. The map, to be published in the journal Astronomy & Astrophysics, is the most detailed celestial map in the field of so-called low radio frequencies. The astronomers, including Leiden astronomers,…

This is an annual series of public lectures at the location that forms the heart of astronomy in Leiden: the Old Observatory.

Leiden Observatory is managed by its Directorate, with assistance from a number of Management Teams, an Institute Council, and an Advisory Board. The Secretariat, the Education Office and the Computer Support Group provide support for its research and educational tasks.

On this section of the website you can find more information about the Old Observatory and the current astronomy research institute.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

Your tuition fee depends on a number of factors, such as your nationality and your previous Dutch higher-education qualifications.
